• Polished stones with smooth edges and no chipped pieces — create an even-looking decorative layer.
• Colorfast, uncoated and non-toxic glass — suitable for aquariums, animals and plants.
• Does not alter aquarium water chemistry — use it as tank decoration without changing the water chemistry.
• Shines in water but does not glow in the dark — bring a blue accent to an aquarium or display.
• Rinse with water 3–4 times before aquarium use — prepare the stones before adding them to a tank.

Use blue glass gravel to add color and texture to an aquarium or to finish a small creative display. Its polished appearance suits fish tanks as well as planted arrangements and decorative projects, while the stone-size range makes it useful for a visible surface layer. For aquarium layouts, plan the amount around the tank footprint and layer depth, then arrange the stones without building them too high or pressing them against the walls.

Is BXI blue sea glass gravel suitable for aquariums?

Yes, BXI blue sea glass gravel is made for freshwater and saltwater aquarium decoration, including betta tanks. The stones are colorfast, uncoated and non-toxic, and they do not alter aquarium water chemistry. Their smooth polished edges help avoid chipped pieces. Rinse the gravel with water 3–4 times before putting it in a fish tank, and avoid stacking it too high or close to tank walls to help prevent harm to fish.

• Use in freshwater or saltwater aquariums, including betta fish tanks.
• Keep the layer low and away from the walls of the tank.

How much gravel is needed for a tank?

For a 1 in (2.54 cm) layer, calculate the tank’s length in inches multiplied by its width in inches, then divide by 23 lb (10.4 kg). A 10 in (25.4 cm) by 10 in tank needs about 4.35 lb (1.97 kg) for a 1 in layer. The bag has a volume of 0.22 gal (0.83 L), so use the footprint calculation to plan how much gravel your layout requires.

• Depth reference: 1 in (2.54 cm).
• Example footprint: 10 in (25.4 cm) × 10 in (25.4 cm).
